Abstract

Adsorption of carrier-free radiotracers 181W and 93mMo produced in the 181Ta(p, n)and natNb(p, n)reactions, respectively, on anion-exchange resin was studied in mixed solution of HF and HNO3 in a concentration range of 10-4 -10 -1 M HF/0.1 M HNO3. Distribution coefficients (K d) of 181W and 93mMo at 70 °C showed the V-shaped variation with the minimum at around 10-1 M HF/0.1 M HNO3, although variation of the Kd values for 93mMowas quite small compared with that for 181W. Formation of oxofluoro complexes for W and Mo is briefly discussed.
